BOOT-CRIME.

Specication of Letters Patent No. 6,794, dated October 16, 1849.

To all whom i may concern Be it known that I, BENJAMIN LIVER- MORE, ofHartland, in the county of Hndsor and State of Vermont, have invented anew and useful Improvement in an Instrument Called a CrimpingInstrument, and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, in which- Figure l, is a perspective view of theinstrument. A, A represents the body of the instrument being an iron inshape resembling the let-ter U, with atriangular mouth or opening in theend of each prong-in which opening the wedges B, B, are placed. Thesewedges conform in shape with the openings, being thickest at C, C, whichis the widest p-art of the mouth or openings and narrowest at D, D,which is the narrowest part of the mouth or openings, the wedges havingflanges on each end to prevent their falling` out when not in use. Thewedges but partially fill the mouth o-r openings, so that when they areplaced back to the widest part of the mouth at C, C, there is a spacebetween the wedges and inner jaws sufficient to admit the edges of theleather. When the edge of the boot front being placed within this spaceand the wedges pressed forward toward D D the instrument retains itshold so firmly as to prevent its being withdrawn-there being grooves cuton the inside of the wedges which prevent the leather from slipping outfrom between the inner aws and wedges.

E, E, is a screw which passes through the body at the center andoperates against the back edge of. the crimping board thus when thescrew is turned causing the body of the instrument to recede and therebydraw the leather on to the crimping board.

To many crimping instruments now in use there are the followingobjections viz, to some it is necessary to cut into the crimping boardin order to get hold of the leather thereby damaging the board which isoften broken in consequence of being weakened by cutting into in orderto apply the instrument-and o-ne now in use similar to the' abovedescribed instrument the objection is to the outer jaw which is made toopen with a screw pressing through the jaws to press the jaws togetherto hold the leather which is very liable to get out of repair, andrequires more time to perform the operation of crimping-and the cost ofwhich is much higher than mine. These diiiiculties are avoided andsurmounted by my improvement. The main part of my instrument is castwhole; therefore, there is no wear or chance to get out of repair andcan be applied to any part of a crimping board without cutting ornotching into the board, the operation of the wedge being much betterthan the screw, being quicker and less complicated in its operation, andthe instrument can be afforded at much less cost.

Having described my improvement and the manner in which I construct myinstrument, what I claim as my invention is- The method of securing andholding onto the leather by means of the wedge operating in the mouthsor openings in the ends of the prongs of the instrument-as hereindescribed and set forth.
